Specification of Letters Patent.

Patented Jan. 23, 1912.

Application filed June 20, 1910. Serial No. 567,802.

To all whom it may concern:

Be it known that I, EDGAR D. MIsNnR, of St. Louis, in the State ofMissouri, have invented certain new and useful Improvements inl\Iolding-Machines and I do hereby declare the following to be a full,clear,

and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

The primary object of this invention is to simplify the construction andmode of operation of molding machines, and particularly those of thetype designed for the manufacture of fuel briquet According to mypresent invention molds or die-housings are circumferentially arrangedon a circular carrier between spaced apart cross members so as to present an approximately unbroken surface in passing beneath an openbottom hopper. These cross members permit the die housings to beoscillated on their respective bearings as they .approach rotaryplungers, and while moving with and away from them, so as to insureproper coperation without the necessity of having the number of plungerscorrespond with the number of housings. Each housing has a series ofdie-openings which accommodate movable dies and receive the plungers.The pressure of the plungers against the material is taken up by shoul'ders of the dies bearing against shoulders of the die-housings, thusrelieving the die actuating cams of the compressing strain. The dies ofeach housing are connected by a common yoke, and the latter is providedwith rollers which travel on cams which force the dies outwardly toeject the material and to hold them in their extended positions as thedie-housings are passed through a water bath,l whereupon the camsrestore the dies to their normal positions.

Each die-opening is provided at its inner end with lateral reliefopenings to allow of the free reciprocation of the dies.

The invention'will be hereinafter fully set forth and particularlypointed out in the claims.

In the accompanying drawings, Figure 1 is a sectional elevation. Fig. 2is a view at right angles to Fig. 1, showing the plunger carrier and twoof the die-housings in section, the other die-housings being omitted.

Fig. 3 is a fragmentary view on an enlarged tween and journaled incarriers 5.

scale. Fig. 4 is a fragmentary plan view on an enlarged scale of some ofthe molds. Fig. 5 is an enlarged end view of a diehousing. Fig. 6 is aview of one end of a die-housing partly in section. Fig. 7 is atransverse sectional view on line 7 7, Fig. 6. l

Referring to the drawings, 1 designates a stationary frame which I have,shown as mounted on a base 2, which is preferably of concrete formationand formed with a water trough 3. In frame 1 is mounted a fixed shaft 4,upon which are two rotary carriers 5 which are shown in the form ofcircular disks connected by spacedapart cross pieces 6.

7 designates a series of circularlyarranged molds or die-housingsmounted be- These die housings normally ll the spaces between crosspieces 6 so that the mold has an approximately smooth unbrokenperiphery. These cross pieces permit the die housings to be oscillatedon their bearings, but when in their normal positions the die housingsare flush with the outer faces of the cross pieces. Each housing isprovided with a series of circular openings 8 wherein are located dies 9having shoulders 10 at their inner ends which are designed to abutagainst stops at the inner ends of the openings. Each die has a rod 12projecting from its inner end and extended through and bcyond the innerend of the housing, and these rods are fitted loosely to a yoke 13,being held by nuts 14. Each yoke carries rollers 15 which travel in camgrooves 17 of two disks 18 xedly -mounted on shaft 4. The cams 17actuate the dies to eject the molded material and hold the dies at theouter ends of the die-openings while traveling through the water bath,and these cams also return the dies to their normal positions.

Each die-housing has at one end a lever 20 which carries a roller 21which travels in a cam groove 22 of a xed disk 23 mounted on shaft 4.The purpose of these levers is to successively oscillate the severaldie-hous ings while revolving.

25 designates a rotary carrier, and 26 a shaft therefor supported byframe 1, the bearings for this shaft being strengthened by brace rods 27so as to hold shafts 4 and 26 in fixed relation to each other. Thecarrier 25 is provided with circumferentially arranged spaced-apartopenings, arranged in rows, and` wherein are located vheavy coiledsprings 28 which act against the inner flanged ends of plungers 29,which latter are held by retaining plates 30.

I have shown a series of twenty-four diehousings, but the exact numberis immaterial, and they are spaced 15 apart. I have shown a series oftwelve plungers spaced 30 apart. AIn consequence of this differencebetween the number of plungers and the number of die-housings, and toavoid any cessation in the rotation of either the die-housings or theplungers, I provide for successively oscillating each die-housing as itis brought into coperative relation to the plungers to allow the latterto enter the molds on straight lines and to effectively compress thematerial before separation, the die-housings and the plungers beingrevolved without cessation. VThe dip in the cam groove is such thateachmold or diehousing will be turned first in one direction, prior tocompression, and in the opposite direction, after compression, and afterthe respective levers pass out of the inwardly extended portion of thecam groove the diehousings will successively resume their normalpositions. not taken up by disks 18, but wholly by the shoulders at theinner ends of the die-openings. After compression the dies will beforced koutwardly by cam grooves 17 acting on yokes 13 to eject thebriquets, and the dies will be drawn inwardly after the housings havepassed from the bath. rIo insure the free reciprocation of the dies eachdie- .housing has lateral openings 31 at the inner ends of openings 8,as clearly shown in Fig. 7 and it is the walls of these relief openingswhich form stops for the shoulders of the dies.

36 designates an open-bottom hopper mounted on frame 1 and extendingover a.

portion of the revolving series o-f moldsA to supply material to theopenings of the several die-housings. Within this hopper I locate aseries of rot-ary agitators 37, which are preferably in the .form ofarms having T-ends. rlhe shafts of the several agitators are gearedtogether, and power is applied Vto one of them and by it communicated tothe others. vThe material is supplied to the hopper from a fluXingheater which may be of'any preferred construction and'provided with asuitable agitator and means for controlling the outlet to the hopper.

Although the rotary series of'molds and plungers may be actuated in anypreferred manner, the gearing shown comprises a driving pinion 41 inmesh with a gear wheel 42 on plunger-carrier shaft 26, said gear Awheel42 communicating power to the ,mold

carriers, through gear wheel 43 afIiXedV to loneof the carrier disks 5.

'the` art.

The compression strain is The operation is manifest from what has thesame with further detail.

The advantages of the invention will at once suggest themselves to thoseskilled in By oscillating each mold as it approaches the rotary plungersa lesser number'of plungers is required, and the entrance of theplungers into the die-openings on straight lines is insured, andfurthermore although the plungers are less in number than the housingsthe time necessary for effecting compression is Anot interfered withnotwithstanding the fact that both the plungers and the housingscontinue to revolve while in engagement. Then, too, it will be noticedthat the pressure of the plungers on the material is not communicated tothe cams by which the dies are operated, lbut is y an open bottomhopper, a rotary suport, series of oscillating die housings carried by"said support, spacing members filling the spaces between saidv diehousings at the periphery of the support to; form, in conjuncltion withthe die housings, an approximately smooth surface at such periphery, inv'9 passing beneath the o-pen bottom hopper, dies movable in saidhousings, a rotary se'- ries of plungers for coperating with such diehousings, the number of die housings being in excess of the number ofplungers, means for Vpositively oscillating the die housings as theyapproach and leave said plungers to insure proper coperation of theplungers with each die housing, and means f or imparting a continuousrotary motion to said plungers and support.
